Tuzoia is an unusual genus of bivalved arthropod that has been classified as a phyllocarid or perhaps as a member of a yet-to-be-named group including other odd Early-Middle Cambrian arthropods. It’s known from North America (British Columbia, Utah, Pennsylvania), Europe, China, and Australia. Yeah, it got around.
